BALTIMORE (WJZ) — A Baltimore City police officer is charged with assault after prosecutors say he struck a 14-year-old boy who was being held on the ground by other officers.

Christie Ileto has more on the charges that officer’s facing.

A Baltimore City police officer is on the other side of the law Tuesday. The state’s attorney’s office is slapping 14 year veteran Serge Antonin with second degree assault charges for allegedly hitting a 14-year-old boy who was in police custody following a crash.

Top brass says “Any officer who engages in conduct that brings discredit to the hard working women and men of the department will be held accountable.”

Sky Eye Chopper 13 caught the aftermath of the pursuit last July 29 that ended on the 19-hundred block of Belair Road.

The teen was driving what police say was a stolen car. It crashed at a used car lot but it was what happened after the crash that police say has the officer in hot water.

“The boy tried to get out of the car and the police grabbed him, threw him on the ground and one police smacked him,” said a witness.

“The message is clear: we will not tolerate officers breaking the law in order to enforce the law,” said an official.

Words from top cops last year that stand true now as Antonin waits for his day in court.
